| Abstract: | Handover is an important basis for ens uring train-ground data transmission of highspeed trains.Failure to handover or abnormal handover may cause wireless timeout or even system degradation in CTCS-3 lines.The basic process of GSM-R wireless network'handover is briefly introduced and the handover test method is also described.Based on dynamic detection data from the comprehensive detection train for high-speed railway,the changing trend of the rate of success in handover over recent years is analyzed.Finally.the reasons of handover failures are given and optimization suggestions are put forward. |
